Abstract (en)
[origin: EP1589304A2] An apparatus for converting a refrigerant pipe of an air conditioner comprises: a valve housing (110) installed at a position where respective refrigerant discharge pipes (11b,12b) of plural compressors are put together, having a valve space portion (111) therein, and having a first refrigerant inlet (112), a second refrigerant inlet (113), a detour refrigerant inlet (116), a refrigerant outlet and a bypass outlet (115) at upper and lower portions thereof; a bypass pipe (120) for connecting the refrigerant outlet of the valve housing to refrigerant suction pipes (11a,12a) of the compressors so that a refrigerant discharged from each refrigerant discharge pipe of the plural compressors can be introduced to the refrigerant suction pipes of the plural compressors; an open/close valve (130) slidably installed at the valve space portion (111) of the valve housing so that a refrigerant discharged from the refrigerant discharge pipes (11b,12b) can be selectively introduced into a refrigerant circulation pipe of a condenser (31) or the bypass pipe (120); and an open/close valve driving means (142,142') installed at the valve housing and driving the open/close valve.
